CASTING INVESTMENT 25 LB PACK
Formulation contains a de-foamer blended right into the material. Gives you low rise when vacuuming, a wider water usage range for greater yield and flexibility, easier removal of air bubbles on wax pattern surfaces and a more free-flowing mix. Molds will have extra strength. Exacting details can be reproduced and break-out accomplished more easily. Complete technical information and specifications are included.
Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. From 5,000 years ago, when beeswax formed the pattern, to today’s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. Lost foam casting is a modern form of investment casting that eliminates certain steps in the process.
The process is generally used for small castings, but has been used to produce complete aircraft door frames, steel castings of up to 300 kg and aluminum castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting, but has lower equipment costs. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
